Subject: [coq_makefile] Enforce warn_error for plugins.

The amount of dangerous warnings in plugins is out of hand, including
some very serious ones.

As Coq developers are maintaining plugins these days it makes sense to
require the contributions to follow the same coding discipline as in
the main tree, thus we require the set of warnings fatal warnings to
be the same in Coq and in plugins.

We don't mark deprecation as fatal as to allow time for migration.

Fixes #6974

+Warnings

+- Coq now builds plugins with `-warn-error` enabled by default. The
+  amount of dangerous warnings in plugin code was very high, so we now
+  require plugins in the CI to adhere to the Coq warning policy. We
+  _strongly_ recommend against disabling the default set of warnings.
